what happens to lean muscle in elderly? - (answers)fat replaces lean muscle,
which leads to decrease in total body fluid
what happens to kidneys as we age? - (answers)- less able to concentrate urine
which leads to fluid loss
- diminished sense of thirst
why do elderly lose fluid? - (answers)- decreased thirst = less intake
- loss of taste = more salt = fluid imbalance
- incontinence = limiting intake
what regulates thirst and intake? - (answers)hypothalamus
sensible fluid loss - (answers)body fluid loss that can be measured, such as urine
output, feces, vomit
Insensible fluid loss - (answers)fluid loss that cannot be measured (sweating)
who is most at risk for dehydration? - (answers)infants and elderly
consequences of overhydration - (answers)Cells burst, bladder infection
